Question

The three vertices of parallelogram are (11) (44) and (48)
find the fourth vertex,

Answer 1

Answer:

Step-by-step explanation:

Consider the unknown vertices as(x,y)

Mid point of diagonal is same for both AC and BD so

Find mid points of A,C

Then find mid points of B,D

Now equal them

U will get the value of the 4 th vertices

Answer 2

Step-by-step explanation:

we know the total sum of interior angles in parallelogram=360

a°+b°+c°+d°=360

11+44+48+d°=360

103°+d°=360

d°=360-103

d°=257
